<B>SYNOPSIS</B>
""" + _SYNOPSIS + """
<B>DESCRIPTION</B>
The cat command outputs the contents of one or more URLs to stdout.
It is equivalent to doing:
gsutil cp url... -
(The final '-' causes gsutil to stream the output to stdout.)
<B>WARNING: DATA INTEGRITY CHECKING NOT DONE</B>
The gsutil cat command does not compute a checksum of the downloaded data.
Therefore, we recommend that users either perform their own validation of the
output of gsutil cat or use gsutil cp or rsync (both of which perform
integrity checking automatically).
<B>OPTIONS</B>
-h Prints short header for each object. For example:
gsutil cat -h gs://bucket/meeting_notes/2012_Feb/*.txt
This would print a header with the object name before the contents
of each text object that matched the wildcard.
-r range Causes gsutil to output just the specified byte range of the
object. Ranges are can be of these forms:
start-end (e.g., -r 256-5939)
start- (e.g., -r 256-)
-numbytes (e.g., -r -5)
where offsets start at 0, start-end means to return bytes start
through end (inclusive), start- means to return bytes start
through the end of the object, and -numbytes means to return the
last numbytes of the object. For example:
gsutil cat -r 256-939 gs://bucket/object
returns bytes 256 through 939, while:
gsutil cat -r -5 gs://bucket/object
returns the final 5 bytes of the object.

# Multi-Dialect Modula-2 Lexer
class Modula2Lexer(RegexLexer):
"""
For `Modula-2 <http://www.modula2.org/>`_ source code.
The Modula-2 lexer supports several dialects. By default, it operates in
fallback mode, recognising the *combined* literals, punctuation symbols
and operators of all supported dialects, and the *combined* reserved words
and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10, while not
differentiating between library defined identifiers.
To select a specific dialect, a dialect option may be passed
or a dialect tag may be embedded into a source file.
Dialect Options:
`m2pim`
Select PIM Modula-2 dialect.
`m2iso`
Select ISO Modula-2 dialect.
`m2r10`
Select Modula-2 R10 dialect.
`objm2`
Select Objective Modula-2 dialect.
The PIM and ISO dialect options may be qualified with a language extension.
Language Extensions:
`+aglet`
Select Aglet Modula-2 extensions, available with m2iso.
`+gm2`
Select GNU Modula-2 extensions, available with m2pim.
`+p1`
Select p1 Modula-2 extensions, available with m2iso.
`+xds`
Select XDS Modula-2 extensions, available with m2iso.
Passing a Dialect Option via Unix Commandline Interface
Dialect options may be passed to the lexer using the `dialect` key.
Only one such option should be passed. If multiple dialect options are
passed, the first valid option is used, any subsequent options are ignored.
Examples:
`$ pygmentize -O full,dialect=m2iso -f html -o /path/to/output /path/to/input`
Use ISO dialect to render input to HTML output
`$ pygmentize -O full,dialect=m2iso+p1 -f rtf -o /path/to/output /path/to/input`
Use ISO dialect with p1 extensions to render input to RTF output
Embedding a Dialect Option within a source file
A dialect option may be embedded in a source file in form of a dialect
tag, a specially formatted comment that specifies a dialect option.
Dialect Tag EBNF::
dialectTag :
OpeningCommentDelim Prefix dialectOption ClosingCommentDelim ;
dialectOption :
'm2pim' | 'm2iso' | 'm2r10' | 'objm2' |
'm2iso+aglet' | 'm2pim+gm2' | 'm2iso+p1' | 'm2iso+xds' ;
Prefix : '!' ;
OpeningCommentDelim : '(*' ;
ClosingCommentDelim : '*)' ;
No whitespace is permitted between the tokens of a dialect tag.
In the event that a source file contains multiple dialect tags, the first
tag that contains a valid dialect option will be used and any subsequent
dialect tags will be ignored. Ideally, a dialect tag should be placed
at the beginning of a source file.
An embedded dialect tag overrides a dialect option set via command line.
Examples:
``(*!m2r10*) DEFINITION MODULE Foobar; ...``
Use Modula2 R10 dialect to render this source file.
``(*!m2pim+gm2*) DEFINITION MODULE Bazbam; ...``
Use PIM dialect with GNU extensions to render this source file.
Algol Publication Mode:
In Algol publication mode, source text is rendered for publication of
algorithms in scientific papers and academic texts, following the format
of the Revised Algol-60 Language Report. It is activated by passing
one of two corresponding styles as an option:
`algol`
render reserved words lowercase underline boldface
and builtins lowercase boldface italic
`algol_nu`
render reserved words lowercase boldface (no underlining)
and builtins lowercase boldface italic
The lexer automatically performs the required lowercase conversion when
this mode is activated.
Example:
``$ pygmentize -O full,style=algol -f latex -o /path/to/output /path/to/input``
Render input file in Algol publication mode to LaTeX output.
Rendering Mode of First Class ADT Identifiers:
The rendering of standard library first class ADT identifiers is controlled
by option flag "treat_stdlib_adts_as_builtins".
When this option is turned on, standard library ADT identifiers are rendered
as builtins. When it is turned off, they are rendered as ordinary library
identifiers.
`treat_stdlib_adts_as_builtins` (default: On)
The option is useful for dialects that support ADTs as first class objects
and provide ADTs in the standard library that would otherwise be built-in.
At present, only Modula-2 R10 supports library ADTs as first class objects
and therefore, no ADT identifiers are defined for any other dialects.
Example:
``$ pygmentize -O full,dialect=m2r10,treat_stdlib_adts_as_builtins=Off ...``
Render standard library ADTs as ordinary library types.

''' Provide the ``Document`` class, which is a container for Bokeh Models to
be reflected to the client side BokehJS library.
As a concrete example, consider a column layout with ``Slider`` and ``Select``
widgets, and a plot with some tools, an axis and grid, and a glyph renderer
for circles. A simplified representation of this document might look like the
figure below:
.. figure:: /_images/document.svg
:align: center
:width: 65%
A Bokeh Document is a collection of Bokeh Models (e.g. plots, tools,
glyphs, etc.) that can be serialized as a single collection.

''' The basic unit of serialization for Bokeh.
Document instances collect Bokeh models (e.g. plots, layouts, widgets,
etc.) so that they may be reflected into the BokehJS client runtime.
Because models may refer to other models (e.g., a plot *has* a list of
renderers), it is not generally useful or meaningful to convert individual
models to JSON. Accordingly, the ``Document`` is thus the smallest unit
of serialization for Bokeh.

will return immediately. Otherwise, ``new_event`` will be appended to
``old_events``.
Args:
new_event (DocumentChangedEvent) :
The new event to attempt to combine

A list of previous events to attempt to combine new_event with
